I combined three 100ml naphtha pulls and left them to evap and saturate before I froze it. Ideally, according to the Q21Q21 tek, I should have evapped to half of that volume, but I spaced out and it evapped down to 75ml from 300ml. My question is , is this bad? They're in the freezer at my friends house so I can't look. Is it good to saturate the solution down that far, or is it possible to harm the yield by evaporating down too far?

Much love nexians

You don't have to freeze precip, you could just evaporate all of the naphta. Freeze precip keeps you from having to slowly evaporate all of the naphtha, and can also help with oxidation issues. Your yield should be fine, but your just wasting solvent.

Honestly i've never evaped any naptha and haven't had yield issues, just reuse the naphtha for the next pull, if your freezer is good and frosty the naphtha will be pretty clear

That should be fine. the dmt is in there so its not possible for it to evap out and in the freezer it will do its thing just the same.
100ml isnt very much naptha though. I use much more than that each pull so let us know how it goes. How much material did you use to extract? Im assuming you used mhrb.

DMT doesnt destroy or dissapear like that.

Some people dont freeze and just evaporate all the way to retrieve their DMT, so for sure pre-evaporating more than the recommeded wont hurt. At most, some DMT will already start crystallizing before you even stick it in the freezer, which wouldnt hurt in any way. It probably will just help making sure your naphtha is saturated enough so that all the DMT crashes out in the freezer

Ive had issues re-using naptha after freez preciping. it tends to hold a bunch of gooey jungle alkaloids that make the dmt sticky and hard to handle when used more than once.

What I do is freeze precip my pulls and save the poured off naptha after ive collected all the crystals. I place a fan on the used naptha and am always surprised how much more is left in there that the freezer didnt get to fall out.
After the naptha has all evaped I take a razor to the pyrex and collect a more jungley spice that is still very powerful but quite tacky and sticky. I keep this evaped spice separate from my snow white crystals for use in my aya or pharma or even to vape. Its just as good but not as pretty and easy to handle and load up.

Hope that helps.

than you all for the succinct replies, my mind can rest
Per the question about how much material I use: I follow the Q21Q21 tek exactly with very good results, so 100g of MHRB and 100 ml of solvent to pull with.

I'm sure there are better variations and other ways of reaching the same goal, but I am new to it so I've been doing it exactly as it reads , and it hasn't failed me yet

Right on! Congards on your first extraction. That makes sense now that you say you only used 100g mhrb. I like to use more naptha than the tek suggests since some gets absorbed in the muck. I dont mind having extra naptha since I precipitate rather than just evap. Id rather have more naptha to ensure it doesnt get over saturated but ive done the tek by the book and it works great.

Would it be advantageous to use more naphtha on 100g of bark in the same tek (Q21Q21)? If so, how much and why?

Also, wow I didn't know crystals could precipitate out without freezing. What's the difference in appearance between freeze precipitated crystals and non-freeze precipitated crystals?

I've usually used 150ml or so per 100g, like olympus mon stated there will be some solvent loss in the bark itself. I've not had the same issues with re-use of the naphtha though, possibly freezer temperature differences? or naphtha brand/heating differences? I get my naphtha pretty close to boiling when doing the pull.

Non freeze precipitated may be larger due to the slower formation. Also they may be yellower due to oxidation, but not necessarily. Be careful with the larger crystal formations though because sometimes solvent may be trapped inside the crystal and unable to evaporate.

oh okay, thank you.

what is over-saturation? what are the dangers of over-saturation?

No risks, I already explained in post #4

oh sorry, i was talking about what olympus said earlier >< something about be careful for over saturation

No you dont need to worry about over-saturation which is when the naptha can not hold anymore dmt. Its not a big concern I just like to use extra just in case. Dont worry you did a fine job Im sure. I dint mean to confuse you.
Cheers

You mentioned something about full evap, but I see you are sticking to freeze precipitation which helps cleanse your products of any remaining impurities.

I agree with SeekerOfTruths when he says you do not have to do this. I personally favor fan-evap or slow evap, which yes, can have oxidation issues, but so long as you watch it and make sure it doesn't sit too long, it's not a big deal. You retain more alkaloids it seems like this way, I could be wrong, but it seems like this is what happens in my experience. Also, in addition to that, you will retain more of your material. It will be yellow and some material might be tacky, but so long as you did not get any mimosa soup in with your naphtha, it will be safe to vape/smoke once all the solvent evaps. I've been heating the soup and also heating the pulls lately and have been getting a maple-like golden color to my spice, and this spice so far has turned out to be the best I've tried! 5 15ml - 20ml pulls off of 40 grams of MHRB and it usually yields about 0.5 - 0.6g's.

I've tried freeze precip once now, and while it did work with pure results, I was not impressed with the quantity I obtained from it. I felt like as much time as i had put into it, I should have gotten more. Call me impatient, but I am usually a sucker for the fruits of my labors.

Congratulations on your first extraction! It'll only get easier and more fun from here on out!
